pertains especially to roller bearing axles or spindles.

The object of the invention is to provide certain improvements in roller bearings for spindles applicable to various mavehicles andv other articles and deichinery,

bearings, spinvices having journals, rotary dles, axles or hubs. v

A further object of the invention is to provide in a rollerbe-aring certain novel and peculiar construction and arrangement of such rollers with relation to an axle or spindle, whereby a more evenly balanced and J uniform'bear'ing is produced.

. axle and its wheel hub 'A still furtherobject ofthe invention is 'to provide in a roller bearing, novel and pe culiar nieansfor holding such rollers in revoluble osition on an axle, spindle or shaft.

A still further object of e invention is tov provide a'fixed shart, axle r spindle with a series of roller bearings having journal bearings loose upon the axle ends, said rollers 'having certain portions revolved against portions of the axle, and certain portions revol ed against portions of the hub of the wheel revolved on said axle.

A still further object ofthe invention is to provide a circular series of rollers for an arranged to revolve on their own axes in loose bearings at the ends of the axle and in contact with the said. axle and the said wheel hub during the revolution of the latter, and to provide thrust rollers rotated by said hub against the'ends of the said axle.

Other objects, advantages and improved results are attainable by and through the construction and arrangement which will be tional view. Fig. 3 is an elevation of theaxle bearings and 3 outer end of the axle with its cap removed. Fig. 4 is a similar view of the other or inner end of the axle. Fig. 5 is a crosssection on the plane indicated by the dotted line m-m, Fig. 2. Fig. 6 is a detail elevation of one of the longitudinal rollers. Fig. 7 is a detail edge. view of one of the cone carrying plates.

The same reference numerals denote the same parts throughout the several views of the drawings.

The invention is applicable to various other axles, spindles, shafts and journals, as here inbefore stated, but'for the purpose of exeinplification and illustration it is shown applied to a non-revoluble vehicle spindle or axle spindle 1. The axle 1 is specially constructed, having a pair of circular bearings 2, and circular end bearings 3 and l, with a space 5 between each of the bearings 2 and their adjacent end bearings 3 and it, and a central space 6 between the bearings 2. The face ends of the spindle have angular bearing surfaces 7 and 8 for double cone shaped rollers 9 and 10, hereinafter to be particularly described.

A circular series of longitudinal rollers 11 surround the axle, each of such rollers having end pintles 12 journaled in rings 13 loose upon the ends of the axle, and each roller has a pair of circular bearing flanges 14 made in the same piece therewith and bearing against the wheel hub 15. The circular flanges l-lare revolved in the spaces 5 without contact with the axle, while the portions of the rollers adjacent each side of the flanges revolve against the axle bearings 2, 3 and 4, so that the portions of the rollers which engage the axle do not engage the wheel hub.

Upon the (alter side of the roller-bearing ring 11:5 are circular plateslfi and 16, having openingsfr and 14) respectively, and lugs 17 in which the double cone-shaped rollers 9 and 10 are journaled. The rollers 9 revolvein the openings 9* against the angular end surface 7 of one end of the axle, and the rollers 10 revolve in the openings 10 against the angular surface 8 of the other or inner end of the axle. The rollers 9 and 10, rings 13, plate 16 and plate 16 are held in proper position within'the hub by caps 18 and 19 which are secured to the ends of the hub and have bearings for the cones like those of the. axle ends. The plate 16 is split or divided in two sections for clamping around the in- I cap 19 by suitable screws 22.

In a journal bearing, the combination, with a suitable hub, an axle spindle. havin angular end faces, a series of lon itudina rollers, and hub-caps having angular bear-. ing faces opposite the spindle faces, of. a series of cone rollers working between the. cap faces'and the spindle faces, a lpair of rings in which the longitudinal rol ersare journaled, and a pair of circular plates in which the cone rollers arejournaled, said plates overlapping the rings to prevent hand in the presence of two witnesses.
